ROTARY ENGINE.

Specification of Letters Patent.

Patented Oct. 31, 1911.

Application filed May-G, 1910. Serial No. 559,669.

' siding at Gold Hill, in the county otJaickson and State of Oregon, have invented certain new and useful Improvements in Ptovtary Engines and I do hereby declare the followingito be a full, clear, and exact description of the invention, such as will enpertains to make and use the same.

rllhe present invention relates to rotary,

engines, and while features of the same may be employed for use in connection with engines operated by steam, compressed air or explosive charges, it is peculiarly adapted for the last named.

The primary object is to provide a simple and compact engine of few parts, said parts being so arranged and constructed that they are -not apty to become'deranged or injured.

An embodiment of the invention. is illustrated in the accompanying drawings, wherein z- Figure 1 is a side elevation of the same. Fig. 2 is an end elevation. Fig. 3 is a v ertical sectional view-on the line 3-3 of Fig. 9 Fig. et is a detail sectional view through the pump mechanism.

therethrough, 4in which is slidably mounted a reciprocatory device 13 provided Vwith terminal blades 14 that are arranged to alternately project. from the periphery of the piston body.

`The cylinder member is provided at one side w'th a' recess or chamber 15, in which is slidably mounted a reciprocatory abutment 16, the inner end of which cooperates with the piston, 'the outer end having a coiled` spring 17 bearing thereagainst to maintain such cooperative relation. In the opposite portionof the cylinder member is .located a cam 1'8 having an inclined 'face 19 that is disposed diametrically opposite tothe abutment. The parts are arranged so that, as indicated in Fig. 3, when one of the blades 14 rides up the inclined face 19, the other blade will be against the inner end of the abutment, and moving outwardly, will move said abutment in a corresponding direction.

The motive fluid isintroduced into the cylinder member through a port 20 located on one side of the abutment 16, and

arranged in said cylinder member on the opposite side of the abutment, is an igniter 21. An exhaust port Q2 opens from the cylinder member contiguous to the inclined face 19 of the cam 18. rThe preferred means Ifor introducing charges to the. cylinder member will now be described. A pump is formed in or upon the cylinder' member, and preferably comprises a cylinder 23, within which operates a recipocatory piston 21 having a piston rod or stem 25 projecting from one end of the cylinder and surrounded by a spring 2G, said spring thus serving to normally maintain the piston at one end of the cylinder' 23. The stem QG has an outstanding lug 27 that reciprocates in a suitable guide 2S, and this lug is disposed in the path of projections Q9 formed upon the inner sides. of certainspokes of a balance wheel 30 that is mounted on the engine shaft S. The explosive mixture brought fromany suitable source (not shown) is conducted to the cylinder Q3 by a pipe 31, in which is located a valvev 82, and the charge is conducted from the cylinder 23 through a conduit 33 to the port 20, a valve 8:1' being located in said conduit-.-

Briefly described, the operation of the engine is as follows. Assuming the parts, as illustrated in Fig. 3, when the outermost' blade rides up .the inclined face 19 of the cam 18, the other blade, as already explained will press against the abutment 16 and force the same outward. At the same time, one of the projections 29 of balance wheel is engaged with the lug 27 of the piston and-Will move the said rod and Consequently the piston against the action ofagainst the wall ot the cylinder member, and the igniter being operated by any well known ineanS, the charge will follow the blade, and inl doing so, pass the abutment 16 as the latter is Ytorced outward byfthe blade and be exploded as soon as the blade passes the igniting means. The torce of this explosion will hold the abutment 16 in open position until the blade has passed the exhaust port 22, whereupon the pressure will be relieved, and the abutment will return to its original position. its the blade that has now been operated by the pressure of the exploded mixture rides up the cam face 19 the opposite blade will be brought into position against the abutment 16, and the action will be repeated. ln connection with the operation ot' 'the pump, it will be evident that the projection 2*) which is engaged with the lug 2T, passes said lng, the latter will be disengaged therefrom and the spring Q6 can act to return the piston to its origi-v nal position, thereby drawing in another cl'iarge, which will be next forced into the cylinder member.

From the Aforegoing, it is thought that the construction, operation and many advantages oit the herein described invention will be ai'iparent to those skilled in the art, without further description, and it will be understood` that vai-ione changes in the size, shape, proportion and minor details of construe tion, may be resorted, to without vdeparting `from the Spiritor sacrilicing any ot 'the advantages ot the invention.

Having thus :fully described my invention, what l claim new, and desire to secure by Letters Patent, i. ;:-v

il. ln a rotary engine, the combination with a. cylinder member, ot a rotary piston having blade operatingin the cylinder nouv/,loo

member, a movable abutment in the cylinder vmember coacting 'with the pistomnieans for conveying a charge into the cylinder member on one side of the4 abutment, and means located on the opposite side of the abutment to ignite the charge after the blade passes the abutment and the igniting,- means, the charge conveyed to the cylinder member following the blade and -passing said abutment upon movement of said abutment in one direction under the action Aot' said blade until it reaches said igniting means when the charge is exploded. i
